Kahola Reservoir Spillway, Chase County, Kansas – I spent some time on Sunday exploring ice formations in the river channel below Kahola reservoir. Great fun, juggling camera, camera case, and tripod while climbing over ice-encrusted boulders as I descended to stream level. But as a payoff, the diversity of patterns in the ice was amazing to see, and it was kinetic art. Bubbles floated slowly underneath crystal formations, and trapped frozen leaves.
The green color in the photo is thick algae below the ice.
